Interactions between electrons in solids often lead to effects that go beyond simple, intuitive pictures of what should be possible. One example stems from the Hall effect, which describes how the ...

Forbes contributors publish independent expert analyses and insights. Covering Digital Storage Technology & Market. IEEE President in 2024 This last week I had my last two public appearances as the ...

A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a ...

In 1947, Shockley, Brattain and Bardeen were investigating the field effect transistor but lead them into inventing the bipolar transistor instead. In 1952, the field effect transistor of Shockley was ...

Normally, semiconductors don't have many free electrons. Since electric current relies on those free electrons, the amount of current that can travel through an isolated semiconductor is negligible.

A field effect transistor (FET) is a carrier device with three terminals: source, drain, and gate. In FETs, an electric field can be applied at the terminal of the gate, modifying the conductive ...

Detailed measurements collected in metropolitan Tel Aviv, Israel, have revealed how the ebb and flow of traffic throughout the week affects the electric field generated by Earth's atmosphere. Led by ...

OTTAWA, ON, Oct. 31, 2025 /CNW/ - Field Effect, a leading innovator in cybersecurity, has officially earned membership into the Microsoft Virus Initiative (MVI)—a distinction reserved for security ...

If you ever work with a circuit that controls a decent amount of current, you will often encounter a FET – a Field-Effect Transistor. Whether you want to control a couple of powerful LEDs, switch a ...

A graphene layer consists of carbon atoms linked by covalent bonds, forming a honeycomb structure. Its excellent electron mobility, chemical and physical stability, electrical and thermal conductivity ...
